如何使用Swig定义和传递ByteBuffer？

ByteBuffer-td6696.html
的一些经过修改的示例，应在进行较小的更改（特别是在

%typemap(in) (char* pchOutput, int*outputSize))

%typemap(in)        (char* pchInput, int inputSize) {  $1 = JCALL1(GetDirectBufferAddress, jenv, $input);   $2 = (int)JCALL1(GetDirectBufferCapacity, jenv, $input); } %typemap(in)        (char* pchOutput, int* outputSize) {  $1 = JCALL1(GetDirectBufferAddress, jenv, $input);   $2 = &((int)JCALL1(GetDirectBufferCapacity, jenv, $input)); } %typemap(jni)       (char* pchInput, int inputSize), (char* pchOutput, int* outputSize) "jobject" %typemap(jtype)     (char* pchInput, int inputSize), (char* pchOutput, int* outputSize) "java.nio.ByteBuffer" %typemap(jstype)    (char* pchInput, int inputSize), (char* pchOutput, int* outputSize) "java.nio.ByteBuffer" %typemap(javain)    (char* pchInput, int inputSize), (char* pchOutput, int* outputSize) "$javainput" %typemap(javaout)   (char* pchInput, int inputSize), (char* pchOutput, int* outputSize) {     return $jnicall; }
